The hardware is here today for people prepared to tolerate mild amounts of latency. It’s easy to forget that computing tasks used to often take major amounts of time - rendering an audio file, rendering a video, transcoding – all kinds of tasks took minutes or even hours of the computer spinning its fans on maximum just to deliver the result. AI and agentic AI and diffusion is the next round of that - trading a small…

Hmm, I have access to A100s and a GB10, but if I use the models hosted there to code, I waste a lot of time waiting for answers and correcting errors. The amount of work I get done thanks to the quality and speed of frontier hosted models let me be insanely productive and have a lot of free time. I could use the slow local setup, but at what price?

Well if all that was taken away from you and you had to go to the bank to ask for the money to rebuild so you could become as productive as you are now, what would that cost and would the bank loan you the money?

This is my opinion too. Even if you buy hardware like a cluster of 8xGB10s or 4 A100s, they'll still be slow and a little dumber than what you're used to. We need to wait a little for better hardware. Lots of companies are pushing the frontier, so hopefully it'll come very soon. Competition and innovation will hopefully make the bubble pop, and we'll get reasonably priced local hardware to run very intelligent models…

The racks we're deploying are effectively GB300 NVL72s: 72 Blackwell Ultra GPUs 36 Grace CPUs, 20.7TB of unified HBM3e. Works out to about 1.1exaflops of fp4. Networking is 800gbps. 120kW per rack.

That’s a majorly impressive computer. What’s the price of that per rack? Deploying for what?

I asked a few of my friends that are ML engineers this question and all of them said to run the LLMs in the cloud with their infrastructure because it was going to be way faster. If you just want to tinker around I would look at @JSR_FDD's comment.

There are more factors than speed though, like: privacy

Next you're going to tell me that car salesman recommend just leasing new cars, doctors recommend just following the standard of care, construction workers just recommend subbing it out, and your tech friends say just use AWS.

If you want a massive MacBook anyway then it's great. They are decent for local LLMs, awesome for local image models and it's a MacBook so AppleCare+ has your back. IMO it's a no brainer if you wanted a MacBook anyway but it's a poor choice if your reason to buy it is to run LLMs.

I agree. To run an acceptable model (e.g. Qwen/Qwen3.6-27B or google/gemma-4-31B) with a good quantization (minimum Q5) with a good context size (min 64k) you could buy 2 or even 3 GTX 5060 16GiB VRAM for ~550$ each. Fyi the much faster MoE models were useless for my usecases - e.g not able to correctly identify me/I/you, endless thinking loops, etc. I'm currently running those models using an RTX 5070 12GiB + RTX 50…

how many tokens per second do you get?

It’s kind of amazing how steadily this question is asked in every forum where it can be asked. Kind of amazing that the answers previously given can’t reach the next person who’s going to ask it.

Isn’t it all rapidly evolving? I guess beyond that it’s a signal of growing interest in local LLMs

If your car salesman friend gives you stupid advice it either means he is stupid or he is not your friend.

What's crazy is these people want to invest decent money to use AI/LLMs, but somehow don't think to just ask an AI chat bot which would easily answer it for them and any follow-up questions.

I sold cars for a decade and wouldn't even take the insanely cheap priced company demo car, just driving my 10 year old car instead.

On that note though, most car salesman are somewhat stupid, although the best ones are atleast normal. (I was a cal mechE grad and top 0.2% nationwide car salesman). They also slowly brainwash themselves into believing most of what they say.

$3-4M per rack. A variety of workloads...
